A Mirror Vanishing Band for Weight Distributions of Binary Linear Codes
Xianmang He
Chen and Xie recently proved, using the Ashikhmin--Barg lemma on minimal vectors, that every binary linear code with () has no codewords of weight in…
Improving the Linkage Construction with Echelon-Ferrers for Constant-Dimension Codes
Xianmang He, Yindong Chen, Zusheng Zhang
Echelon-Ferrers is an important method to improve lower bounds for constant-dimension codes, which can be applied on various parameters. Fagang Li [12] combined the linkage constru…
New Construction for Constant Dimension Subspace Codes via a Composite Structure
Xianmang He, Yindong Chen, Zusheng Zhang +1
One of the most fundamental topics in subspace coding is to explore the maximal possible value of a set of -dimensional subspaces in such tha…
Construction of Const Dimension Codes from Serval Parallel Lift MRD Code
Xianmang He, Yindong Chen
In this paper, we generalize the method of using two parallel versions of the lifted MRD code from the existing work [1]. The Delsarte theorem of the rank distribution of MRD codes…
Construction of Const Dimension Code from Two Parallel Versions of Linkage Construction
Xianmang He
The linkage construction and its generalization is one of the most powerful constructions for constant dimension code, accounting for approximately 50\% of all the listed parameter…
New Constructions of Subspace Codes Using Subsets of MRD codes in Several Blocks
Hao Chen, Xianmang He, Jian Weng +1
A basic problem for the constant dimension subspace coding is to determine the maximal possible size A_q (n, d, k) of a set of k-dimensional subspaces in Fnq such that the subspace…
New -ary Quantum MDS Codes with Distances Bigger than
Xianmang He, Liqing Xu, Hao Chen
Constructions of quantum MDS codes have been studied by many authors. We refer to the table in page 1482 of [3] for known constructions. However there are only few -ary quantum…
